主要是测试https://solidity-by-example.org/defi/uniswap-v2-add-remove-liquidity/中的这个例子，向Uniswap V2的WETH/USDT流动性池添加或删除流动性。
分叉测试方法
使用foundry新建一个项目： forge init AddRemoveLiquidity
合约源代码放在src目录，命名为UniswapV2Liquidity.sol，测试代码放在test目录，命名为UniswapV2Liquidity.t.sol ，
另外，为了使得调试信息更为直观，使用了console.sol进行日志输出：
- 合约中引入，
import "forge-std/console.sol"; foundry.toml配置文件中启用 ffi = true ,允许 Foundry 运行本地命令和输出日志。- forge test
-vvvv选项来启用更高的日志级别，这样调试信息才能被打印出来。
最后，运行forge test -vvvv --fork-url https://eth-mainnet.g.alchemy.com/v2/ACCESS_TOKEN --fork-block-number 20623798，fork主网，设置指定区块号，执行分叉测试。
